Recently, blockchain was introduced into the cyber-physical systems, which provides services of privacy and trust. However, reliability and system performance issues exist when blockchain and cyber-physical systems are integrated. In this paper, we design a blockchain-enabled cyber-physical system, where a new blockchain consensus is used to solve the problems of reliability and system performance. Firstly, an autonomous consensus mechanism called Proof-of-Weighted-Planned-Behavior is established based on the theory of planned behavior. Then, the behavior of consensus participants gets further explained by introducing credit evaluation and vulnerable node analysis. Moreover, considering the Jain fairness index, a dynamic authorizer group mechanism that coordinates reliability and decentralization is developed. By optimizing the credit threshold of the authorization group, the security and reliability of our designed mechanism are guaranteed. Finally, the experimental simulation results prove that compared with the traditional consensus, our proposed consensus improves the reliability and the system performance of the blockchain-enabled cyber-physical systems.
